Can you not just return the instance without knowing what "Generic" properties are defined????

Question The create function should just return the instance of the object, who cares about shape used to define it.

Instead of:

container .bind<CognitoJwtVerifierSingleUserPool<{ userPoolId: string; tokenUse: 'id' | 'access' }>>(IocSymbols.Authorizer) .toConstantValue(CognitoJwtVerifier.create({ userPoolId: APP_ENV.userPoolId, tokenUse: 'id' }));

Use: @inject(IocSymbols.Authorizer) private readonly _authorizer: CognitoJwtVerifierSingleUserPool<{ userPoolId: string; tokenUse: 'id' | 'access' }>,

public handler(....) { this._authorizer.verify(authToken); <----- this throws an error because it can't interpret the values }

Intended:

container .bind(IocSymbols.Authorizer) .toConstantValue(CognitoJwtVerifier.create({ userPoolId: APP_ENV.userPoolId, tokenUse: 'id' }));

Use: @inject(IocSymbols.Authorizer) private readonly _authorizer: CognitoJwtVerifier>,

public handler(....) { this._authorizer.verify(authToken); <---- inject the instance and properties are set }
